bushing of a bearing so arranged that these I grooves are directed toward one another and unite at a determined point of the brasses. These grooves which, are preferably of screw or helical arrangement, are connected with a lubricator from which they can receive a continuous supply of. -lubricant.

The. lubricant is driven by the motion of the journal forward through the grooves to the junction of the latter where thelubricant is distributed overfthe journal. lubricant is then carried by the journal to "an outlet communicating with the lubricator and is forced thence by the pressure existing 1 in the bearinginto the lubricator. -Tl1is arrangement reduces the loss of lubricant to a minimum, in fact almost to nothing, because it is constantly compelled to travel toward the center of the bearing and .to beret-urned into the lubricator.
